Since 1988, Larry Sultan has returned time and again to photograph on porn sets in Los Angeles's San Fernando Valley - the Silicon(e) Valley of the porn industry. But 'The Valley' is by no means a documentary on porn filmmaking. Rather, it is a dense series of pictures of middle-class homes invaded by the porn industry. Sultan's lens focuses on pedestrian details - a piece of half eaten pie, dirty linens in a heap, "actors" taking a break - that offer clues to a bizarre other-world.
